GP Test Cyp 250 is an injectable steroid manufactured by Geneza Pharmaceuticals. It contains 250mg per ML of the hormone Testosterone Cypionate. Bodybuilders using GP Test Cyp 250 often find that a twice weekly injection schedule is very sufficient for maintaining steady blood levels of the hormone. GP Test Cyp 250 is similar to Testosterone Enanthate even their half liveand active life periods are different, they are similar. Testosterone is the most common anabolic hormone. Therefore bodybuilders often consider it the base steroid to most all cycles. Users of GP Test Cyp 250 notice a dramatic gain in muscle size and strength, as well as an overall sense of well being and increases libido and sex drive. Testosterone aromatizes very easily and therefore estrogen buildup and side effects can become an issue for users sensitive to these problems or those choosing to use a high dose of this compound. Therefore bodybuilders frequently take testosterone with an anti-estrogen such as Anastrozole, Proviron, Tamoxifen to help keep estrogen related side effects to a minimum. Extremely sensitive users, or users using very high doses (800-1200mgs) might find that stronger anti-estrogens such as Letrozole or Exemestane are more suitable. Testosterone use will quickly shut down the body/s natural production of the hormone, thus making a proper PCT plan essential for restoring the body/s natural function and maintaining gains as best as possible after use of the steroid has been discontinued. At cycle/s end, bodybuilders often choose to use a combination of Clomid, Tamoxifen, and HCG for a period of 3-4wks in order to restore pituitary gland and testes operation quickly and effectively. Female bodybuilders often use testosterone to build mass, although of course the dosage is significantly less than what males would use due to the possibility of masculizing side effects. The male bodybuilder/s dosage of this steroid would typically be in 400-1200mg per week range and cycle duration would be from 8-20 weeks, depending of course on the goals of the athlete. Women typically see desirable results from doses of 50-100mgs per week.
